Problems solved by technology
[0004] 1. The intermediate frequency power cables and control cables used in mobile intermediate frequency equipment usually need to be used at the same time. For the operator, it needs to be laid twice, and it needs to be closed twice. It is not easy to operate, and it also increases the operating time and labor. strength;
[0005] 2. Since the cable core of the control cable is provided with a layer of metal shielding layer, during the long-term retraction and winding process, the metal wire of the cable shielding layer is easy to break, and the insulation of the cable is punctured, which affects the continued use of the control cable;
[0006] 3. The conductor section of the control wire core is small, and the tensile performance is poor. During the winding process, the conductor in the center layer is the main force point, which is easy to break and will affect the service life of the cable;
[0007] 4. The weight of the two cables is relatively heavy, not suitable for use on ships

Embodiment Construction
[0019] Such as figure 1 The shown integrated intermediate frequency cable for ships includes a cable core, and an outer sheath 10 with a thickness of 0.75-1.5mm is extruded outside the cable core; The power core and 6 control cables 6 with center-symmetrical structure are twisted together, and the control core and the intermediate frequency power core are set together, so that two different types of cables can be fused together, which can play a single cable The dual-purpose function greatly facilitates laying and retracting, and in this way, compared with the method of using the two cables separately, the overall weight of the cable is reduced, which is more suitable for use on ships;
[0020] Wherein, the control cable includes a control cable core formed by twisting three control wire cores, and a carbon fiber wire 5 with a thickness of 0.35-0.5mm is extruded outside the control cable core. It plays the role of shielding, and makes the shielding layer not affect the normal...

Abstract
The invention discloses a composite immediate-frequency cable for a naval vessel. The composite immediate-frequency cable comprises a cable core, wherein an outer sheath which is 0.75-1.5mm thick is extruded outside the cable core; the cable core is formed by twisting seven power line cores and six control cables; a '1+6' structure is adopted by the power line cores; and a central symmetry structure is adopted by the control cables. The composite immediate-frequency cable for the naval vessel has the advantages of light weight and small sections of control line cores, is free of a rupture phenomenon and is applicable to the naval vessel.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a comprehensive intermediate frequency cable for ships. Background technique [0002] At present, the cables used by intermediate frequency equipment used on ships are usually dedicated intermediate frequency cables, including intermediate frequency power cables and control cables. At present, the intermediate frequency cables and control cables used on intermediate frequency equipment are laid separately. The intermediate frequency power cable usually has a seven-core structure, that is, a 1+6 structure. This type of cable has good flexibility and is suitable for use in the working condition of retracting and winding, while the core section of the control cable is small and the control signal transmitted It is also small and susceptible to external influences. Therefore, a metal shielding layer is usually provided outside the core of such control lines. [0003] At present, the ...
